Strangely, I found out that my cheap mini USB Logitech wireless mouse does work, so I have been using that as a workaround. I don't know why it should be different as I thought all USB mice were pretty much standardised as far as drivers are concerned.

After Googling the kernel option that you suggest, I am guessing that the wireless mouse is a USB 2.0 device, whereas the G5 wired mouse is only USB 1.0, which would explain why the wireless mouse works, but the G5 doesn't. I hope this is the case. _________________Intel i7 3820 - 16GB Corsair DDR3 - GeForce GTX 660 2GB - SBLive - 13TB - Gentoo - KDE4

It work before, but some day ,i crash something in kde, and the mouse
can't work

If you turn on the Transaction Translation and your mouse stops working again, you need to turn _off_ the OHCI HCD, and UCHI HCD (usb 1.1) support items.

The Root Hub Transaction Translator and Improved Transaction Translator scheduling items move the USB 1.1 support into the EHCI (usb 2.0) support driver. If you have that enabled _and_ the O/UHCI then the drivers will fight it out and periodically reset/mute/bone the 1.1 devices.

So if you have one on, you have to turn the other off. Your choice.

Note that you may have to play around with this because the transaction translator is in the hardware (at least in part) and if your USB hardware support is bad the old drivers might be better.

Hi. Though this is an old thread the information here was very helpful to me. I had similar problem with blocking wireless mouse after suspend and your advise about turning off OHCI and UCHI HCD helped a lot. Thanks!
